Analisa Kinerja Bandul Vertikal dengan Model Plat pada PLTGL
Sumber energi seperti energi fosil yang semakin menipis. Hal ini mendorong semua pihak untuk dapat menjadi lebih baik hingga ilmu yang terdapat didalam dunia perkapalan dapat melahirkan inovasi terbaru, salah satunya adalah pembangkit listrik tenaga gelombang laut – sistem bandulan. Ponton yang menggunakan sistem bandul adalah salah satu alat yang digunakan untuk mengkonversi dari energy laut menjadi energi listrik. Dalam kajian ini menggunakan kondisi uji onshore tanpa menggunakan ballast dan uji off-shore dengan ballas. Dari kajian ini didapatkan banyaknya putaran yang dapat dihasilkan bandul dengan variasi bentuk sudut juring, tebal plat juring dan sudut kemiringan ponton. Untuk uji on-shore daya terbesar didapatkan pada pengujian dengan menggunakan sudut juring 60 o, tebal 3 mm,sudut kemiringan 60 o daya yang dihasilkan 0.107 watt. Untuk pengujian offshore pada ballas 12 cm, 15 cm,17.5 cm, daya terbesar dihasilkan pada ballas dengan daya 0.124 watt pada juring, tebal, dan sudut kemiringan yang sama dengan pengujian onshore. Jumlah putaran dengan waktu, pada pengujian on-shore yang menghasilkan nilai paling besar pada juring dengan sudut 45 o, tebal 2 mm sudut kemiringan 45 o nilai yang didapatkan 1,176 rad/s. Pada pengjuain off-shore paling besar ada pada ballas 17.5 dengan 1.93 rad/s
Holographic Data Storage Technology- The future of Data Storage
In the present times technological advancement has grown at rapid rate. Today most of the people are using smart devices which comprises of various kinds of technologies. One of the most important factor in using technology is to store digital data. Presently most of the work are done using digital devices such as computers and mobiles and people need to store their data in devices but the device has limited amount of storage. So need arises to store more amount of data using less space. For this purpose we need to invent storage technologies which helps people to store more amount of data. In order to meet demands of greater storage there are various storage technologies such as different types of ROM, optical storage discs, USB flash drives which uses different technologies to store data. This paper focuses on Holographic data storage technology which helps people to store large amount of data

Optical Variability of the Black Hole Candidate GX339-4 (X1659-487, V821 Ara) - Limits on Periodic Modulation
We present results of extensive CCD optical photometry (over 1000 frames representing ~150 hr of integration time) of the optical counterpart of the X-ray source GX339–4 obtained during the high (soft) state. The source was seen to be significantly variable. We do not, however, detect any periodic modulation with semi-amplitude greater than ~0.03 mag for periods less than ~0.5 day or semi-amplitude greater than ~0.07 mag for longer periods. An optical spectrum obtained shortly after GX339–4 made a transition from a ‘low’ to a ‘high’ state is also presented and compared with previous results. The width of the He IIλ4686 emission line in the spectrum implies that GX339–4 does not have an unusually low inclination angle and we therefore conclude that the orbital period of GX339–4 is probably longer than ~0.5 day

The origins of individual differences in how learning is expressed in rats: a general-process perspective
Laboratory rats can exhibit marked, qualitative individual differences in the form of acquired behaviors. For example, when exposed to a signal-reinforcer relationship some rats show marked and consistent changes in sign-tracking (interacting with the signal; e.g., a lever) and others show marked and consistent changes in goal-tracking (interacting with the location of the predicted reinforcer; e.g., the food well). Here, stable individual differences in rats' sign-tracking and goal-tracking emerged over the course of training, but these differences did not generalize across different signal-reinforcer relationships (Experiment 1). This selectivity suggests that individual differences in sign- and goal-tracking reflect differences in the value placed on individual reinforcers. Two findings provide direct support for this interpretation: the palatability of a reinforcer (as measured by an analysis of lick-cluster size) was positively correlated with goal-tracking (and negatively correlated with sign-tracking); and sating rats with a reinforcer affected goal-tracking but not sign-tracking (Experiment 2). These results indicate that the observed individual differences in sign- and goal-tracking behavior arise from the interaction between the palatability or value of the reinforcer and processes of association as opposed to dispositional differences (e.g., in sensory processes, 'temperament,' or response repertoire)
